Brick-Machines, of which the following is.

a specification. v j

My invention relates to improvements in brick making machinesmand more particularlyto machines for making silica brick, the primary object of the invention being to provide improvements of this character which will dispense with the necessity for the hands touching the stock during the en-.

tire operation of. forming the brick.

A further objectis to provide an im proved table over which the molds are moved between adjustable guide rails, and

during such passage are subjected to the action of a press, a slicker, and an ejector.

A further ob ect is to provide an improved press under the complete control of the operator for pressing the stock into the molds.

A. further object is to provide an iinproved mechanism which 1 term a slicker, which serves to smooth the stock in the molds.

A further object is to provide an improved ejector for, forcing the brick out of the mold.

A further object is to provide an improved car or carrier adapted tomove the moldsalong the table from oneoperation to the next, and so on.

A further object is to provide an imof le lers, gearing, and

proved arrangement power transmission for cdntrolling the op l eration of the several mechanisms.

With these and other objects in view,

of construction and combinations and arrangements of: parts, as will be more fully hereinafter described and pointed out in the claims. i

1, represents a table or platform which may be constructed in various ways, is hollow and on its upper plate or surface two guide rails 2, 2, are positioned, are located parallel to each other and serve as guides for brick molds 3, one of which'isillustrated in Fig. 3. These rails2, 2, are adjustably held by set screws 4, which project through threaded openings in lugs 5 at the sides of the table,'and b T means of these screws the rails 2 may desired distance apart so as to accommodate any ordinary size of mold. 1

\Vhile I refer to part 3as a brick mold,

it is to be understood that the same comprises a plurality of brick molds which are open at top and bottom, the top of table 1 serving as a bottom for the molds while the bricks are being formed.

At the right hand end of the table 1, referring particularly to Figs. 1, 2, 4, and5, is located my improved press which will now be described in detail A frame ,6 is secured on the table, andis connected atthe top by acrossrod! on which a lever or walking beam 8 is pivotally sup- This lover or walking beam comprises an open framework, and

.atqi 'ts forward end is provided with pins 9 e positioned the v which project into slots 10 in the upper ends ofstandards11,.the lower ends of said standards secured to a heavy block or bar 12, which serves as a presser to crush the stock into the molds. These standards 11 "25 on a forked lever 26, the latter fulcrumed:

project through openin in a cross bar 13 l tion to the carrier, a movement of the caron frame 6, so as to gui e the vertical movenor on its rails w ll cause the frame to enment of the presser. gage the mold which PIOJGCtS slightly above The lever'or walking beam 8, at its rear rails 2, and move the'lnold longitudinally 5 end, is connected by downwardly project, of thetable from one position to another, as ing arms 14', with crank pins 15 on wheels for example, from the press to the slicker, 16, the latter secured ,to a'shaft 17 supportand from the sl1cke r to the e e ctor, the ed in bearings 18 on table 1. Thisshaft 17 means for moving said carrier being hereis driven by a belt 19 which connects a drive ina-fter described in connection with the 10 pulley 20- on the drive shaft 21, with a pule ector. l 7a ley 22 on'shaft'17. Drive'shaft21 is sup The part wlnch smooths the brick, and ported in hangers 23,- and is of sufficient which refer to as the slicker, is located length to extend throughout'the machine approximately midway the endsof the so as to drive all of the several parts. The table 1, and is supported upon a frame 40.

.5 walking beam or lever 8 is.also provided at- This frame 40 provides a rotary mounting M its rear end with counter-weighted arms 24, for two parallel screw-threaded rods 41. On which serve to counterbalance the presserone end of each of these rods 41, gears 42 block or bar 12. I

The belt 19 above referred; to is loose, and in mesh therewith, a third gear 43 is 10- 20 unless tightened will slip on the pulley 22, cated' and secured upon a short shaft 44 85 and not drive shaft 17, hence the press will supported in frame 40. These gears 42, and be idle. ,To tighten this belt and start the 43, are of the same diameter and are turned press, a pulley is provided and is located between the runs of the belt and supported drive pulley 46 on drive shaft 21 with a pulley 47 on one of the rods 41. A cross 90 bar 48 is provided at its ends with blocks 49 having semi-circular screw-threaded faces f engaging the screw-threads of rods 41. These blocks 49 are adjustably connected.

betweenits ends on brackets 27 secured to table 1. The forward end of this lever 26 is connected by a llnk 27 w1th a rod 28, and said rod 28 connects with a hand lever 29 pivotally supported at its lower end inbracket 30. This lever 29.is located in 0on venient reach of the operator, so that he may by manipulating this lever, start and stop the press at will.

Themold containing the stock is posi -50, and the said cross bar is connected by a hanger 51 with a block 52 located centrally below the same.

53, represents a car which is mounted on rails 54, and is provided with rollers 55 lo-' 100 cated above and below the rails, so, that the car is prevented from vertical movement. T is car 53 is located directly below the in this position, lever 29' is moved so as block 52 and the bar 51, and is provided to tightenthe belt 19 and cause the press to with the cross bar 48 by means of set screws 95 reciprocate up and down crushin the stock, centrally with a guide sleeve Q6 in which 105 and forcing it into allparts 0 the moldwa vertically movable shaft 57 IS mounted. After the pressing operation is completed, This'shaft 57 is bored atits ends as shown the mold is slid along the table 1 to a point at 58 to receive and 'key a'shaft 59 which under a smoothing mechanism'which I term projects through the block 52, and is held a slicker, and, to'facilitate thismo-vement-pf mgalnst longitudinal movement in the block," 119' the mold, I provide a car or carrier 32 which is in the form of a table having uprights or legs 33, said uprights or legs 33 provided hence, these shafts 57, and 59, telescope relatively to each otherwithin certain limits.

On the upper end'of shaft 59, a beveled gear 60 is sccuredand meshes with a beveled gear 61 on a Sl)()1t shaft 62 supported in the hanger 51 and provided with a pulley 53 which is located above but in frictional contact-with a longitudinally disposed belt 64, the latter' supported upon pulleys 65 mount- ,cd in hangers 66 011 frame 40. One of these we shafts 65 is provided atits end with a beveled gear 67 meshing with a similar gear 68 on the short shaft 44, so that the belt 64 is driven by means of the gears'42 and 43 above described. On the lower end of the shaft 57,,a disk 69 is secured. by means of a set screw 70, This disk 69 provided with 0 below rails 35 supported on the platform 31 above referred to.

Elevated bars or brackets 31 are provided to support the rails 35' above referred to. 11 top of the carrier 32 a swinging frame 55 361's pivotally mounted on a pin 37, and is adaptedto swing horizontally so that the frame 36 may lie longitudinally of the carrier or at right angles thereto,-"and when at right angles to the carrier, will project across the table and inthe path of the mold BEST AVAILABLE cuvi I rectangiilarplate 7 which constitutes the the-slicker, v I
